Summary
On January 03, 2019, a Robinson R44 (N4246Z) was involved in an incident near Grace, ID. All 1 person aboard were uninjured. The aircraft sustained substantial damage.
The National Transportation Safety Board determined the probable cause of this incident to be: The pilot's failure to maintain clearance from the power lines.
The helicopter pilot reported that shortly after liftoff to the north from his property, he observed coyote tracks and "wanted to inspect."
